position relative and right property
提问by Chapsterj
I always thought by setting the div to relative and right 0 would position the div all the way to the right, if its parent was 100% width. Apparently I'm wrong and only absolute works like that. So is there no way to make it work with relative?
我一直认为通过将 div 设置为 relative 和 right 0 会将 div 一直定位到右侧，如果其父级为 100% 宽度。显然我错了，只有绝对的作品才会这样。那么有没有办法让它与亲戚一起工作？

You have to set the parent to be relative, and it's child to absolute positioning.
您必须将父项设置为相对，而将子项设置为绝对定位。
.parent{
position: relative;
width: 100%;
}
.right{
position: absolute;
width: 200px;
height: 200px;
background: red;
top:0;
right:0;
}
? Like here: http://jsfiddle.net/willemvb/n9Vrv/

There's a way to make it work to a relative.
有一种方法可以让它对亲戚起作用。
One way is first to set the parent of the display to inline-flex.
一种方法是首先将显示的父级设置为inline-flex。
Next, set the element (child) position:relative; margin-left:auto; right:0;.
接下来，设置元素 (child) position:relative; margin-left:auto; right:0;。

Correct. Relative positioning is the position offset from where it would be with static positioning.
正确的。相对定位是相对于静态定位的位置偏移。
You need absolute positioning to position with respect to the edges of the containing block.
您需要绝对定位才能相对于包含块的边缘进行定位。
